(1 point) Take the system x' = 4x – xy, y = 5y + x2. How many critical points are there? What is the critical point with the largest x-coordinate? ( The linearization at this point is | tion at this point is [*] =A (Where A is where A is ul A = At this point the behavior is For behavior write one of "saddle", "source", "sink", "spiral sink", "spiral source", "center".
Consider the differential equation: (7y sin(xy) + 2 sec x) dx = (2 lny – 4x sin(xy))dy Note: Do not use square brackets in your response, use normal parantheses if you have to, i.e "0" Then aM ду and ƏN ax Is this equation exact? Yes No Consider the differential equation: sin(x)dx + 5y cos(x)dy = 0 Which of the following can be an integrating factor to make the equation exact? Select all that apply.

a) Find the gradient of f(x, y, z) = 4x + 8y + 3z – 24 and indicate it at point P = (0,3,0) Draw the function in 3D, draw the plane that is generated when f(x,y,z)=0, start with the lines on the xy, yz, and xy planes. X у
Direct Proof For ∀x ∈ R, if 0<x-3 then 7< 4x. Prove by contraposition For ∀x,y ∈ R, if x+5 ≤ y+2 then x ≤ y. Prove by contradiction For ∀x,y ∈ R, if xy< 4 then x<2 or y<2.
